John, Following on from your note on the Brecon Railways Exhibition On an investigative trip to the Sennybridge area I was told of the failed attempt to build a connection from the Brecon/Swansea line to connect with Builth Wells, apparently the money ran out when difficult tunnelling was experienced up the Cillenni valley, they just closed off the tunnel and left everything buried, whatever that means. I wonder if the Breconshire Local & Family History Society (BLFHS) could confirm this and the likely date Regards Roger M Evans
